He asks you for help

“Son,” Greg groans, clearly exhausted. “I can’t go anymore... We need to find a way to get your cum outta there. I love watching you have sex with Mel, but I just don’t think it’s right to have her carry another man’s baby.”

You’re slightly disappointed that he doesn't intend to compete with you, and only wants to prevent your seed from taking root. Your small frown disappears as an idea occurs to you.

With an innocent smile, you look Melanie’s tired body up and down. “I have an idea that just might work.”

“Let’s hear it,” Greg replies, sitting up and looking at you curiously. “What’s the plan?”

“I came really deep inside Mommy,” you begin. “Deeper than you can reach.”

“Yeah, I could feel that the whole while,” Greg chuckles.

“Well, since she’s not taking any pills, and I’m not going to wear protection,” you continue, “I figure the best way to stop her from getting pregnant would be to scoop it out!”

Greg stares at you for a moment before laughing. “That makes sense, but what are we going to use to scoop it out with?”

“Well, I could always use my dick, since we know it’s long enough to reach that far inside." You pause, shooting him a grin. "Or... You could always just lick the stuff out.”
